We are migrating database from HP to AIX. Data is all on SAN.I can do it through RMAN convert. What I want to know is if it is possible to move data at storage level without using Convert command?
View 2 RepliesI am new to oracle which command do I use to set the file storage in oracle? I learnt the we have the option of specifying the storage pattern as per our queries.

We have this archicture:
OLPT DB --> OLPT DB (Physical Standby, active dataguard) --> Data warehouse DB
We only allowed to connect to OLPT DB (Physical Standby, active dataguard) from Data warehouse DB. If there is possibility to use some of Oracle "native" method of data extraction (replication) from OLPT DB (Physical Standby, active dataguard) to Data warehouse DB.
As far as I know we cannot create materialized view log in OLPT DB (Physical Standby, active dataguard) in order to do data replication, but maybe there is some others ways?
I am working in a bank as an system consultant, i have a SAN Storage Area and oracle as below.
SAN 1
This interface includes the DATA FILES of the oracle tablespace
SAN 2
SAN1 Mirrors the DATA FILES of the oracle tablespace to SAN 2
1. Can i rely on real time data recovery from SAN2 ?
2. if SAN1 (Data Files are currupted) will the SAN2 Data Files will be currupted as well.
3. If the SAN2 is currupted then what Oracle Features can be used to have uncurrupted data.
whether Oracle has any capability of automatically checking which lossless compression algorithm it should apply by analyzing a data stream on data load? Does Oracle have any compression advisors/wizards that would make recommendations as to type and level of compression?
View 3 Replies View RelatedI have to move data from old tables into new tables. I use a sqlplus script and execute multiple 'insert from select'. I thought the SQL statements are executed in sequence, one after the other. I run into this problem: Let's take this script for an example
insert into A (a,b,c,....
select a,b,c......
from X;
insert into B (a,b,....
select a,b,....
from A joined with Y;
commit;
After executing the script in our development DB
select count (*) from A
returns 200
When the script is executed in production, A table record count is 5
select count (*) from A joined with Y; (used in the second insert)
returns 200.
It seems that the two statements are executed at the same time and table A is not fully populated when the select in statement two is executed.I suspect this is due to parallel execution in production.
Will executing
ALTER SESSION DISABLE PARALLEL DML;
ALTER SESSION DISABLE PARALLEL QUERY ;
The requirement details are as below,
1) The database contains static as well as transactional data for telecom domain.
2) We have to move region-wise data from one database to another.
3) There are around 10 regions.
4) The region wise data extraction from source db is based on around 40 to 50 tables. Rest of the tables contains static data & it will not change.
5) The volume is around 1 million subscribers per region.
6) The migration is required because
a) The client is upgrading its base product which uses this database
b) There is a change in structure of static tables
c) Hardware upgrade
d) The client want to start with single region on new database & rest of the regions will be operated from old database.
7) Keep execution time to very minimum.
I am thinking to have solution as below,
1) Create destination database with upgraded db structure (as mentioned in 6b)
2) Create database links to access source db in destination db.
3) Write SQL queries to fetch data from all the respective tables for a specific region
4) Write separate PL/SQL blocks for each table to fetch data from source db & insert into respective table in destination db
a) Use FOR ALL & bulk collect to improve the performance
b) Divide table data into multiple chunks & execute parallel batches (around 10) to insert the data
5) Validate pre & post counts to verify the success of migration
I have database A and B , we are strictly restricted to not to create any DB links between these database. In database A based on complex logic we in a stored procedure we populate the data to table type..now dot net will take this table type data and insert the same in database B.
Question here :
1.When we try to bulk collect all the data into table type , i am getting error operand exceeds limit, but it is mandate to put all data in one short to table type as dot net will take that and insert into B database.
2.Is there any good logical method to achieve this in a simple way.

I have two tables with almost the same columns. Table A has 50 columns, Table B has 51 columns, which are defined exactly the same except one more column as LOAD_TIME.
Is there any easy way for me to move the data from Table A to B? the Extra column LOAD_TIME will be set as current system time. All I want is to avoid list all 50 column names. The following SQL has error ORA-00923 error.
INSERT INTO TB_B
SELECT *, sysdate from TB_A;
I have a range partitioned table with one lob column. Each partion is on a separate tablespace except two partitions which are on same tablespace. Now I want to move a partition from one tablespace to another tablespace along with lob data. By using a simple alter table move partition will also move the lob data or there is some special procedure to adopt.

I have to move the data from a Varray column to a table.
Lets say I have created a Varray as described below,
create or replace TYPE "BT_TYPE" AS OBJECT (
R_ID NUMBER,
P_EVENT VARCHAR2(100))
/
create or replace TYPE "BT_VR" AS varray(20) of BT_TYPE
/
And I have a used this Varray as the column datatype in table
Create table BT_MASTER(
BT_ID_SEQNUMBER(5),
BT_DETAILBT_VR);
And this table contains data.
I want to move the data in the VARRAY column BT_DETAIL to another table. I have create a staging table BT_STG which contains a surrogate key column and the columns from the VARRAY. I am creating this staging table at run time.
Create Table BT_STG(
BT_STG_ID NUMBER(5),
R_ID NUMBER(5),
P_EVENT VARCHAR2(100)
);
One way to create this staging table is to query the data dictionary views to get the VARRAY object's columns, datatyeps and create it.
Is there any other simpler way by which I could create a table similar to a VARRAY/Object?
Something similar to,
create table test as select * from BT_VR
My organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?
I am using SQL developer 2.1 to migrate tables from Sybase 12 database to oracle 11g. I have used online data move option for moving sybase data into oracle tables, but even after data move is completed not all rows have been moved from sybase tables to corresponding oracle tables. Some rows are missing but still there is no error message being displayed, how to find out what's going wrong.

View 9 Replies View RelatedLet me explain in detail. I have three tables
1. Emp Table: Columns-> EMPID and DeptID
2. Dept Table: Columns-> DeptName and DeptID
3. Team table : Columns -> Date, EmpID1, EmpID2, DeptNo.
There is a stored procedure which runs every day, and for "EVERY" deptID that exists in the dept table, selects two employee from emp table and puts them in the team table. Now assuming that there are several thousands of departments in the dept table, the amount of data entered in Team table is tremendous every day.
If I continue to run the stored proc for 1 month, the team table will have lots of rows in it.
The real problem is when I want to retrive data for a employee(empid1 or empid2) from Team table and view the related details like date, deptno and empid1 to empid2 from emp table.
How do we optimise the data retrieval and storage for the table Team. optimize the query and data retrieval time from Team table.

the result is Hours.Minutes.
I am trying to minus the two dates and find the time taken for a particular section( eg, unalloc ).
I tried using three union queries .
Select block,timestamp From (
Select 'Unalloc' As Block ,col1,col4 From table_1
Where col2 = 'Batch Started' And col3 = 'proc_unalloc' And
Parms Like '1345'
Union
Select 'Unalloc' As Block ,col1,col4 From table_1
Where col2 = 'Unalloc Ended' And col3 = 'proc_unalloc' And
[code].....
I will minus the start and end time for unalloc to get time taken for un alloc. Then i will minus end time of unalloc and end time for alloc to get time taken for alloc... like wise for metric.
